Under California law, the charges are considered “wobblers,” which means they can be classified as either felonies or misdemeanors depending on the discretion of the district attorney.

The Santa Clara County district attorney will next determine whether or not Foster is formally charged.

While Foster was in custody, the Santa Clara County jail database listed his bail amount at $75,000. By 6:35 p.m. PT Sunday evening, Foster's name no longer registered on the jail's database. A search of various indexes returned the message “person not in custody,” which typically corresponds with an inmate's release on bond.

According to the most recent Santa Clara County bail schedule, the basic bail set for each of Foster's arrest charges is $25,000, and that adds up to his $75,000 bail amount for all three of them.

According to a release from police, the incident happened at about 9:15 a.m. on Sunday morning, and “police responded to a residence on Shannon Rd. in regard to a welfare check and possible disturbance call for service.” After an initial investigation, Foster was arrested. Police say the investigation is ongoing.

According to the Mercury News' Robert Salonga, a woman with whom Foster has been in a long-term relationship accused Foster of throwing her belongings onto a front walkway and balcony, and then physically dragging her in an attempt to remove her from the home.

Salonga also reported that police discovered a SIG Sauer 516 short-barreled rifle inside the home as part of their response to the domestic disturbance, after the woman advised that there should be at least two AR-15 automatic weapons in the house on a 911 call.

That particular weapon is not on the list of illegal AR-15 variants in California, but without certain modifications, it may still fall under violation of state law. Further details on the particulars of the gun confiscated from Foster are not currently available.

“The San Francisco 49ers organization is aware of the report regarding Reuben Foster,” the team said in a statement. “We take matters of this nature seriously and are gathering all pertinent information.”

Almost exactly a month ago, on Jan. 12, Foster was arrested in Alabama and charged with second-degree marijuana possession, a misdemeanor. That applies when someone possesses the drug “for his personal use only.”

Since Foster's urine sample at the 2017 NFL scouting combine came back as diluted, a result that the league treats as a positive test, he was already in the substance abuse policy's intervention program. The program's guidelines punish each subsequent drug-related offense — whether it be a positive test or an arrest — on an escalating level of fines and suspensions. Foster's situation with regard to the Alabama incident is fully explained here.

The next developments for Foster with regard to this current arrest are expected after the investigation is finished. It's worth noting that former 49ers cornerback Tramaine Brock was arrested on suspicion of domestic violence on April 7 of last year. Although prosecutors ultimately dropped charges against Brock, the 49ers released him within 24 hours of his arrest.

Even if criminal charges are not ultimately brought against Foster for this incident, he may still face discipline from the NFL as a result of the league's Personal Conduct Policy.

According to this policy, violations that involve domestic or dating violence will, on first offense, “subject the offender to a baseline suspension without pay of six games with consideration given to any aggravating or mitigating factors.”

The assault weapon portion of Foster's arrest and the January misdemeanor marijuana charge that he currently faces in Alabama may both be considered “aggravating factors” by the NFL. At the very least, the Personal Conduct Policy states that Foster will be offered counseling paid for by the league.

Beyond that, the policy states that the NFL will investigate this incident and determine whether or not Foster should face the baseline six-game suspension.

Prior to being drafted No. 31 overall by the 49ers and delivering a promising rookie season in 2017, Foster was sent home early from the NFL combine after getting into an argument with a hospital worker. Foster had reportedly grown impatient with a long line for medical exams. His urine sample from this combine is the one that later came back as diluted.

This story will be updated as more information becomes available.
